Pigment Selection for Radiative Heat-Dissipating Coatings
This article investigated in detail the effects of carbon black,carbon nanotubes,graphene,copper chromium black and their additives on the thermal stability and infrared emissivity of radiation heat-dissipating coatings.Based on the application scenarios,the design principles of radiation heat dissipation coating formulations were discussed.The results show that copper-chromium black pigment is better than the carbon nanotube and graphene pigment as used in radiative heat-dissipating coatings under high temeprature environment more than 450 ℃.The three pigments have similar application performance as used under middle and low temperature environment between 150 ℃ and 300 ℃.These research results are useful for coatings formula de-sign and selection for different temperature environment
